It could be a mortal man. In Greek mythology, gods sometimes had affairs with mortals. Maybe a particularly handsome and charming mortal catches Hera's eye. He might be a great hero or a simple shepherd with a pure heart.
Perhaps a new, made - up character in the fanfiction. The author could create a unique being, maybe a hybrid of different mythical creatures, who has a special allure that Hera cannot resist. This new character could bring a fresh twist to the story of Hera cheating on Zeus.
Another storyline could be that Hera is tricked into cheating on Zeus. A cunning deity or magical entity manipulates her emotions and makes her believe she is in love with someone else. As she gets involved with this new love interest, she realizes she has strayed from Zeus and then has to deal with the consequences of her actions.
One possible reason could be that in the context of the fanfiction, Hera is tired of Zeus' constant infidelities. She might have reached a point where she just can't bear to deal with him anymore, so she chooses to ignore him as a form of self - protection.
Hera was Zeus' wife. Her main role was to be the queen of the gods. But in their relationship, she was often the one trying to keep Zeus in check due to his many affairs.
The relationship changes in terms of emotional connection. Hera's ignoring Zeus might mean that the emotional bond that was there (even if it was a tumultuous one) is starting to break. This could have far - reaching consequences in the fanfiction world, like affecting the balance in the pantheon or causing other gods and goddesses to take sides depending on how they view Hera's actions towards Zeus.
Perhaps in a fanfiction, Zeus, in a fit of anger over Hera's interference in one of his mortal affairs, uses his power to ostracize Hera from the other gods for a time. This makes Hera feel isolated and hurt, and she has to find a way to regain her standing while also dealing with the betrayal of her husband. It could show her strength as she overcomes this difficult situation.
In this fanfiction, Naruto's appearance might be different. Since he is the son of two powerful gods, he could have a more majestic look. His eyes might glow like lightning or have a special color. His story could involve him trying to fit in with the normal ninjas while also coming to terms with his divine parentage. He might face discrimination from some who fear his power, but he overcomes it with his kind heart, just like in the original Naruto story.
Some of the minor gods who feel overshadowed by Zeus and Hera might be antagonists. In this fanfiction, they could see Percy as a symbol of the over - dominance of Zeus and Hera. They might plot against Percy to send a message to his parents. These minor gods could use their unique powers and their knowledge of the magical world to create all sorts of problems for Percy, from cursing him to setting up traps in his path.
Zeus was powerful and dominant. He was the king of the gods and had a lot of freedom in his actions, which unfortunately often included being unfaithful. Hera was strong - willed and jealous. She couldn't tolerate Zeus's affairs and would fight back.
One possible plot could be Percy discovering his new parentage of being the son of Zeus and Hera. He might struggle with the new identity as it goes against what he previously knew. For example, he could face challenges from the other demigods who are suspicious or jealous of his new status. He then has to prove himself worthy of this new heritage while also dealing with the complex politics among the gods.
It could be a new character introduced specifically for the fanfiction. Maybe a mysterious stranger who has some ulterior motives and targets Bill because of his relationship with Harry.
